Solar Panels in South Africa


Solar panels convert the suns light into energy to provide electricity for residential or commercial buildings. They are manufactured from a combination of many smaller solar cells. The solar cells are spread out over a wide area to catch the suns light. It then sends the current back to the inverter which converts the light to usable energy.

An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night.


Solar Panel Prices in South Africa


The cost of solar panels in South Africa varies depending on several factors such as the brand, size, type, and installation costs. Prices range between R1800 for a 360W Solar Panel and R4200 for a 550W Solar Panel.

On average, a typical 3kW solar panel system in South Africa can cost between R45,000 to R70,000, while a 5kW solar panel system can cost between R70,000 to R110,000. These prices may also vary based on the region and the installer.

It’s important to note that while the upfront cost of installing solar panels may seem high, they can provide significant long-term cost savings by reducing or even eliminating the need for traditional grid electricity.

When considering the cost of solar panels, it’s also important to factor in their lifespan and maintenance costs. With proper installation and maintenance, solar panels can last up to 25 years or more, providing consistent energy savings throughout their lifespan.

How Many Solar Panels do I Need to Power my House?


The number of solar panels you need to power your house depends on a variety of factors, including your energy usage, the size and orientation of your roof, and the efficiency of the panels you choose. To get a rough estimate of the amount you’ll need, you can follow these steps:


  1. Determine your daily energy usage in kilowatt-hours (kWh). You can find this information on your utility bill or by using an online energy calculator.
  2. Calculate the size of the solar system you’ll need by dividing your daily energy usage by the average daily output of a solar panel. The average output of a solar panel is around 300 watts per hour, or 0.3 kilowatts per hour (kWh/h), so a 3-kilowatt solar system could produce around 10 kWh of electricity per day.
  3. Take into account the efficiency of the solar panels you choose, as well as factors like shading and the orientation and angle of your roof. These can all affect the amount of energy your solar system produces.
  4. Consult with a professional solar installer to get a more accurate estimate based on your specific situation.


As a rough estimate, a typical home in South Africa might need between 18 – 30 solar panels to generate enough electricity to power the entire house. However, the exact number of panels you’ll need will depend on your individual circumstances.

How Long do Solar Panels Last in South Africa?


The lifespan of solar panels in South Africa can vary depending on a number of factors, including the quality of the panels, the conditions they are exposed to, and the maintenance they receive. However, they are designed to last for at least 25-30 years.

Most manufacturers offer a warranty that guarantees that their panels will maintain a certain level of performance for a specific period of time, typically 25 years. This means that even after 25 years, they should still be producing a significant amount of electricity.

Overall, while the lifespan of solar panels can vary, most panels are designed to last for at least 25-30 years and can continue to produce electricity well beyond that timeframe.


Clean, Renewable Energy Sources


Besides the fact that solar panels in cape town makes it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the use of solar power is that it is both a clean and a renewable source of energy.

With the advent of global climate change, it has become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of greenhouse gases. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for decades when properly maintained.


Monocrystalline Solar Panels in Cape Town


Monocrystalline solar panels are a type of solar panel made from a single crystal of silicon. They are known for their high efficiency and sleek, black appearance.

The manufacturing process for monocrystalline solar panels involves growing a single crystal of silicon from a seed crystal. This results in a panel with a more uniform structure and higher efficiency than polycrystalline, which are made from multiple smaller silicon crystals.

Monocrystalline solar panels typically have an efficiency rating of between 18% and 22%, which means they are able to convert a higher percentage of sunlight into electricity compared to other types of panels. This high efficiency makes them a popular choice for residential and commercial solar installations where space is limited.


Polycrystalline Solar Panels in Cape Town


Polycrystalline solar panels are a type of solar panel made from multiple smaller silicon crystals. They are known for their lower cost compared to monocrystalline, but slightly lower efficiency.

The manufacturing process for polycrystalline panels involves melting raw silicon and pouring it into a mold to form square blocks. These blocks are then sliced into thin wafers, which are used to make solar cells.

Polycrystalline solar panels typically have an efficiency rating of between 15% and 18%, which means they are slightly less efficient than monocrystalline. However, they are still an effective way to generate electricity from the sun.

Polycrystalline solar panels are a popular choice for larger solar installations, such as commercial or utility-scale projects, where the lower cost can make a significant difference in the overall project budget. They are also a good choice for homeowners on a budget who want to install a solar panel system.


Series vs Parallel Wiring


Parallel circuits have multiple paths for the current to move along. If an item in the circuit is broken, the current will continue to move along the other paths, while ignoring the broken one. This type of circuit is used for most household electrical wiring. For example: when you turn off your TV, it doesn’t also turn off your lights.

When wiring in parallel, the amperage (current) is additive, but the voltage remains the same. eg. If you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps, the entire array would be 12 volts and 20 amps.


Series circuits have only one path for the current to travel along. Therefore, all the current in the circuit must flow through all the loads. A series circuit is a continuous, closed-loop – breaking the circuit at any point stops the entire series from operating. An example of a series circuit is a string of old Christmas lights – if one bulb breaks, the whole string turns off.

When wiring in a series, the voltage is additive, but the amperage remains the same. eg. If you had 4 solar panels in a series and each was rated at 12 volts and 5 amps, the entire array would be 48 volts and 5 amps.
